Linneus, which had been shot at Kingsbury. ‘Two pairs of this 
species of Wagtail were seen by Mr. Bond near the reservoir in the 
early part of the present month, and, although they were very shy, 
that gentleman, who furnished Mr. Yarrell with the specimen ex- 
hibited, succeeded in shooting three of them, two males and one 
female. 
M. Leonard read a paper on the intelligence of animals, which he 
illustrated by means of two pointer dogs which he had trained for 
the purpose. 
To show that these animals possessed the power of comparison, he 
placed different objects upon the ground, such as a glove, a roll of 
paper, a small box, &c., and having kept similar objects himself, he 
showed them one after another to either of the dogs, and desired the 
animal to fetch that which was like it from the ground. The dogs 
performed this task correctly, and all others which they were desired. 
Cards, with numbers from 1 to 9 painted upon them, were placed 
upon the ground, and the dogs fetched any particular number they 
were bidden: a number brought, M. Leonard ordered the dog to 
take back again and exchange for another number, and at the same 
time to deposit it in the place of that number. The dogs also se- 
lected a card of a particular colour, when desired, from among many 
of different colours. Pieces of bread were placed on the ground, and 
in placing them, their master called them by the names of different 
numbers in an irregular manner, and afterwards ordered the dogs to 
fetch the piece of bread he had called a certain number. These and 
various other experiments (some with pieces of meat) were all per- 
formed correctly, and tended to show the great intelligence of the 
animals and the control which their master had obtained over them. 
The dogs were named Phylax and Braque, and either dog, upon his 
name being called, performed the task he was ordered; but one of 
them appeared to be more quick than the other.
